What precautions when using industrial water wall corrosion coal fired boilers? Mainly to provide the industrial production of energy and other power production in order to maintain a power device of its manufacturing operations, one of which is a major steam-powered electricity or gas to maintain the use of industrial boilers, another is based on coal providing power to maintain the operation of the production as raw materials by recycling waste heat boiler traditional industries, it is widely used in industrial production. So, when people use professional industrial boilers need to pay attention to what matters it? First, the operating personnel in the use of industrial boilers operate not only need to have the relevant knowledge and proficiency in operating skills, but also in the operation of the boiler should be run strictly prohibited without leaving their jobs so that the boiler is in a state of neglect, reduce accidents caused by the furnace excessive pressure or pot water level is too high and so on. Second, the staff undergo a rigorous technical evaluation before the relevant professional departments should be adjusted to improve the working pressure in the industrial boilers, pressure gauge and a safety valve to avoid common cause failures industrial boiler overpressure phenomenon appeared to mislead the operator allowed to adjust make mistakes, we should also strengthen the operational skills related to operating personnel so that timely treatment is not a normal phenomenon during boiler operation. Third, before use should be fully checked industrial boilers and boiler configuration check voltage is in the normal current value, the structure of the boiler to avoid unreasonable or poor welding quality and safety accessories related failures caused by the occurrence of industrial boiler runtime accident while before using the boiler should also be adequate treatment in order to be able to reduce accidents during the operation running. These are the three issues of professional industrial boilers in the use of the relevant operators should be noted, strict attention to its use handling precautions can effectively avoid improper operation caused an accident when using a boiler, while improving industrial production to a certain extent efficiency, selected first-class industrial boiler manufacturers can better protect their quality in the selection of industrial boilers used in industrial production.
Our horizontal CFB steam water wall corrosion coal fired boiler for sale has various types: coal fired CFB steam boiler, biomass fired CFB steam boiler. This basic mode of operation is found in most every steam boiler, but there are a few modifications that have been created for different purposes. A superheated boiler takes the standard process and further heats the steam, increasing the temperature and energy output, and it commonly is used to rotate large turbines. Water tube boilers replace the large tank with a series of water-filled tubes that can reach boiling faster and give off more steam.
Fangkuai water wall corrosion coal fired boiler operation advantages 1, large font display water temperature, easy to grasp the boiler and system operation conditions, water temperature from 10 ℃ to 90 ℃ can be set at will, the boiler automatically to the system heating or to provide the user with hot water for bath. 2, the control system controls the start and stop of the circulating pump according to the furnace water temperature, when the furnace water reaches the set upper water temperature, the hot water circulating pump starts, and the hot water circulating pump stops when the water temperature is lower than the set lower temperature. 3. The horizontal gas-fired bath boiler is a three-way full wet back structure. It adopts the design of large furnace and coarse smoke pipe to increase the radiative heat absorption of the furnace and effectively save energy and reduce consumption. Use of threaded smoke pipes and Waveform furnace tank, greatly enhanced the heat transfer effect, greatly saved fuel consumption. 4, the whole machine is also equipped with overheat protection (when the furnace water temperature is super high, the burner automatically stops working and beeps to alarm, and the secondary overheat protection (when the boiler shell temperature exceeds 105 ℃, the secondary circuit is automatically cut off), When the boiler water is lower than the very low water level, the boiler stops working and gives a buzzing alarm), and the boiler leakage protection (the control system detects the electrical leakage, and when the short circuit is short, it will automatically cut off the power supply). 5, the boiler is designed according to the normal pressure structure, the boiler is in a pressure-free state, there is no danger of safety. Use of advanced centrifugal glass cotton multilayer protection Temperature, famous white color steel plate for outer packaging, less heat loss, beautiful anti-rust.
01. The gas-fired boiler should pay attention to the following points during operation: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace, because it is easy to burn out the coal hole cover. (2) the bottom floor of the gas-fired boiler shall not be watered up to prevent damp corrosion. 2, gas-fired boiler operation every 2 weeks, should be checked. 3, gas-fired boiler operation every 3 months after 6 months, the furnace should be shut down for comprehensive inspection and maintenance. (1) check the gas boiler inside and outside, such as the welds of the compressed part, the corrosion phenomenon inside and outside the steel plate, if found serious defects should be repaired in time, if the defects are not serious, it will be repaired the next time the furnace is shut down. If any suspicions are found but do not affect production safety, records should be made for future reference. (2) after inspection, the boiler primer may be coated on the surface of the water to prevent corrosion. 4, gas-fired boiler and boiler base paint at least once a year. 5, gas-fired boiler maintenance method: dry method and wet method, shut down for more than one month, should adopt dry maintenance method, shut down for less than one month can be used wet maintenance method. (1) dry maintenance method: after the boiler stops the furnace, put away the boiler water, thoroughly remove the internal dirt, rinse it out, dry it in the furnace with a slight fire (pay attention not to fire), and then it will be 10 mm in diameter and 30 mm in diameter. The small lump of quicklime is divided into plates, placed in the pan, without contact with the metal, and the weight of quicklime is calculated at the volume of 8 kg per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed, Check every three months, if the quicklime is broken, replace it, and remove quicklime and tray when the boiler is re-in operation. (2) Wet maintenance method: after the boiler stops the furnace, it gives out the furnace water, thoroughly removes the internal dirt, rinses it, reinjects the treated water to the full, heats the furnace water to 100 ℃, lets the gas from the water drain out of the furnace, and then closes all the valves, Protection is not allowed in cold climates Wet curing method, lest the furnace water ice damage the boiler.
Boiler Corrosion is slow poison for Industrial Boilers. Corrosion is a phenomenon in which atmospheric oxygen in the air or water reacts with the metal to form oxides. Corrosion in industrial boilers is a phenomenon in which the oxygen that is dissolved in the water inside the boiler reacts with the metal of the steam boilers.Online chat
